B-LINE 444 RTSC NK – Frequently Asked Questions

1) Can the Eaton B-Line 444 RTSC NK junction box be mounted outdoors?
Yes. The 444 RTSC NK is rated NEMA 3R, so it handles rain, sleet and falling dirt on an exterior wall. It ships with a rain hood and plated screws for that use, and the carbon steel body carries a painted ANSI 61 grey finish. NEMA 3R is not a washdown or hosedown rating, so skip it where the box will take direct pressure spray.
2) Does this 4x4x4 B-Line enclosure come with knockouts for conduit?
No. The NK in 444 RTSC NK means no knockout, so every conduit entry gets drilled or punched on site to suit your fitting. That is the usual choice on a 3R box, since you control where the penetrations land and can keep them low or on the bottom face to stay weathertight.
3) What size is the B-Line 444 RTSC NK enclosure inside?
It is a 4 x 4 x 4 inch cube: 4 inch height, 4 inch width, and 4 inch length/depth. That is the standard small pull-and-splice footprint, and the box weighs 1.9 lb, so a single surface fastener pattern carries it easily.
4) How does the cover come off on the B-Line 444 RTSC NK box?
Screw cover, flanged type, held with plated screws. You need a driver to open it rather than a hinge or latch, so it suits a junction or splice point you rarely reopen. If your maintenance crew needs tool-free access several times a year, look for a hinged or clamped-cover enclosure instead.
5) How is the B-Line 444 junction box fastened to the wall?
Surface mounting through embossed thru holes in the back of the box. The embossed holes keep the fastener heads off the mounting surface so water does not track into the interior. Wall fasteners are not part of the box, so pick anchors to suit your substrate.
6) How heavy gauge is the steel on this B-Line 3R junction box?
16 gauge carbon steel, painted ANSI 61 grey. That is a commercial-duty wall thickness for a box this size, and the grey finish matches the standard grey used across most industrial control enclosures, so it blends with existing gear on a plant or building exterior. Painted steel will need touch-up if scratched in a coastal or corrosive setting.
7) Where is the Eaton B-Line 444 RTSC NK made?
United States. That matters on public and institutional work where domestic-origin material is written into the specification.
